The Dallas Cowboys couldn't get the job done in what most people around the NFL thought would be the ultimate reality check for them.After dominating subpar teams for the past couple of weeks, they had to face an Arizona Cardinals team craving a win after three straight losses.The Cardinals hung on to a 25-22 lead and Kyler Murray improved his record in the AT&T Stadium to 8-0. Arizona limited Dak Prescott to just 226 yards, although he did throw for three touchdowns.Mike McCarthy Isn't WorriedEven if the Cowboys failed to live up to their toughest task yet, coach Mike McCarthy doesn't feel like it was a measuring stick kind of game:“I didn’t view it as a measuring stick (game),” McCarthy said, per The Athletic. “I think we know who we are, and I think we have confidence that we can win any game, anywhere. I think we’ve illustrated that so far this season."“Our focus was tight, it was about winning and improving. Our penalties were too high, time of possession (was an issue), and they made, frankly, a couple of more big plays than we did," McCarthy added.Dak Prescott Lauds The Cardinals' Defensive PlanPrior to the game, Cardinals star Budda Baker claimed that the best way to limit Dak Prescott was by simply disguising coverages.When asked about those comments, the gunslinger had no choice but to give the Cardinals credit for their game plan:“They definitely did that,” Prescott said. “I feel like every team I play does that more than they do (against) other guys, I guess you could say. It’s just important for me to watch my film study and then see the post-snap. I think I did a solid job of it. They did a good job disguising, trying to show some blitzes and then got out of there, brought a couple of them. They did a good job of getting their hands up on some DB pressures, batting the ball down."Prescott Says He's Not Discouraged By The LossEven so, Prescott didn't feel discouraged by his team's loss. If anything, it only boosted his confidence in his team's ability to bounce back:“Not discouraged,” the QB sentenced. “Definitely disappointed we didn’t come away with the win, but damn sure not discouraged. I know the team we have, what we’ve got. Just simply didn’t get it done as a team, starting with myself, (I’ve) got to be better. All of us, we’ve got to look at ourselves in the mirror and find a way to come out with a win in a game like this."Dak Warns Cowboys RivalsPrescott said that he and his teammate aren't afraid to go against any team or even play on the road, warning their future rival not to sleep on them:“Whoever it is (we face in the playoffs), line them up. We’ll play them here, we’ll play them at their place, their backyard, wherever. I’ve got a lot of confidence in this team," Prescott said, per ClutchPoints.Ironically, their rival might as well be the Cardinals, as both teams are 11-5 and would face off if the postseason started tomorrow.
